here is how I would do it (wich resembles what christian said I think)
on installing the programme --> store the current date
everytime the programme starts --> store the current date in second location
now on startup off you'r programme you do 2 checks:
first check to see if the current date is before the date stored in location 2
if so --> user had turend clock back and trial ends
if not --> do check 2
check to see if the current date isn't 15 days after the date stored at location 1
if so --> trial has ended
if not --> store date in location 2 and start programme
to keep the user from hacking you'r programme (or at least make it harder too do) you might want to encrypt the date's
hope this helps
Credit to Christian who gave me this idea and I think this was also what he meant in his reply
If my help was helpfull let me know, if not let me know why.

I need help!!
An Application that was written by someone before me used the Infragistics controls. These controls have expired and my company have now purchased the full licence.
How can I change the licence in the solution? When I build the solution I get an "Unable to resolve type" error. The file being referenced is the Licences.licx.
Can someone please give me advice as to fix it? I am on a very very short deadline...
Thank you in advance!!

You should speak to Infragistics tech support. This question has nothing to do with the VB(.NET) language.

I created user control and dropped textbox over there.
I want the control to use all degault properties which windows Textbox provides + defined by me
right now it doesn't show even text property !

If you inherit the textbox class then U will be able to use all the default properties of text box
Hope this will help you

Is it possible to persist the current com component (that is to prevent other programs from re-registering a different version of the same component).
Thanks
|
|
|
|
|
No. Usually, an older version of a component won't replace a newer version. But there is nothing to stop a newer one from replacing an older version of a component.

In my application I am using tabbed browsing because there are multiple forms in my application. Each tab has a form. I noticed that when I added a table adapter to the form the binding navigator was added to the form, not the tab page.
Do I need to use the binding navigator?
I noticed that when I delete the binding navigator I get errors and then the form designer will not come up.
I am going to have to add multiple table adapters to this one form, possibly multiple table adapters to one single tab page.
Will it add multiple binding navigators or can I use the same binding navigator with multiple table adapters?
I have another post on here that shows the errors I am getting when I get rid of the binding navigator.
The subject line of the other post is "Problems with Designer Generated Code in VB 2005"

The Binding controls apply to the form, not an individual TabPage. Tabs are just an organization container for visual controls.

It will add multiple navigators to the form, one for each table to you drag onto it.

Hi!,
I'm trying to pass arguments to a running process, the process is started from my program and takes command line arguments on start up, but I wish to pass more over time, not just on start up.
Does anyone know if this is possible, and if it is where should I be looking?
Thanks 
John

of course this is possible, and there are many ways of achieving it. You could use:
- .NET Remoting
- sockets
- named pipes
- memory mapped files
and many others I guess.
Some of these will also work between machines.
For passing a command line to another process, I tend to prefer named pipes.
all but the first are Windows features, available for a long time and in all languages.
For more info you could search Google, MSDN, or CodeProject. I'm confident CP holds articles
on all of them.

Hi,
Thanks for the reply, just a few questions. Are named pipes supported in .NET?
From the examples I could find quickly, it would seem these are look like server/client applications, is this how they work?

j_foulkes wrote: Are named pipes supported in .NET?
AFAIK they are not supported, I used P/Invoke to the good old Win32 functions.
They work like UNIX pipes, their names are system wide, so two processes can decide
to connect to the same pipe based on a fixed name; and a pipe is like a socket, what
gets written at one end can be read at the other end. So I would call it a symmetric
connection, not necesseraly associated with client/server stuff.
I used named pipes in a singleton application: the first instance creates the pipe and
listens for commands; if a second instance gets launched with some command line,
it pipes that command to the first instance and exits again.

What process?? Is it something you wrote?? Do you have control of the source code??
If not, then if this is possible or not is entirely up to the application you are launching, not you. If it doesn't support doing this already, there's nothing you can do to add this support to it. You'd have to rewrite this app yourself, duplicating it's functionality, and adding this communication support to it.
